Not really sure if this is what you are looking for but just try this.
AR System Administration>Application>Users/Groups/Roles>License Review
In Manage User Licenses page give
User Category>Aplication Registered User
Licensed Application>Remedy Incident Management
This would pull up all user along with there write license as fixed or floating
Similarly you can find out for all registered Applications.
Hope this is what you are looking for.
From the Home Page navigate to AR System Administration Console -> System -> General -> Add or Remove Licenses form
Here you can see the number of fixed/floating licenses for applications. You can also take a report by clicking on Generate License Usage Report button to see how many licenses are in use.
